Recall 11V127 covers 4,664 2007-2012 Kenworth trucks with loose PACCAR MX oil filter caps. Repair is free at any franchised Kenworth dealer.

Kenworth is recalling 4,664 2007-2012 trucks, including T700, T2000, T660, T800, and W900 models equipped with PACCAR MX engines, because the oil module centrifugal spinner filter cap can loosen and release engine oil. Oil discharged onto hot exhaust components raises the risk of a fire, and the dealer repair will be free once available.

What's wrong?

On affected 2007-2012 Kenworth trucks with PACCAR MX engines, the oil module centrifugal spinner filter cap is the cover for a spinning oil filter inside the engine oil system. That spinner filter helps separate contaminants from engine oil, and the cap keeps the filter chamber sealed while oil moves through the module.

In this recall, the spinner filter cap can loosen. If the cap comes off, engine oil can partially discharge from the oil module and land on hot exhaust components. The recall does not identify a separate owner-visible cause for the loose cap, so the problem centers on the cap staying secured during normal engine operation.

There is no warning sign before failure. If oil has already discharged, an owner can notice oil on engine components, oil smell, smoke from hot exhaust areas, or a low oil condition, but the recall does not describe a reliable early warning before the cap comes loose.

Who's affected?

Covers multiple heavy-truck model lines across the 2007-2012 model years, all tied to the fuel tank assembly.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

Engine oil can discharge onto hot exhaust components when the engine is under significant load, causing a fire. If your VIN is included, schedule the repair and avoid heavy engine load until a dealer completes it. Repair will be free at any franchised Kenworth dealer once available.

What should I do?

  1. Check your VIN to confirm your 2007-2012 Kenworth T700, T2000, T660, T800, 388, 389, 387, 384, 367, W900, 587, 320, 365, 330, or 386 is included in this recall.
  2. Watch for owner notice or dealer guidance before scheduling if your dealer has not opened the repair for your VIN.
  3. Contact a franchised Kenworth dealer about the free oil-module filter-cap re-torque and secondary-retention-device installation that keeps the spinner filter cap secured.
  4. Reference recall number 11V127 when you call the dealer.
  5. Avoid heavy engine loads until the repair is complete because loose oil-module caps can let engine oil discharge onto hot exhaust components.

What happens at the repair

At the dealer, a Kenworth technician re-torques the oil module filter cap on the PACCAR MX engine. The technician also installs a secondary retention device on the secondary centrifugal spinner filter cap so the cap stays secured. The recall notice said this service was free of charge and was expected to begin during March 2011. If your VIN is included, ask the dealer to confirm parts and service availability before arranging the repair.
